It seem it was working find. Now since i turn on the heat for floors the hot water temp has gone way down. The programer seems to be flashing Have any ideas?

Give me a few minutes to pull the specs for your boiler

What controls the DHW zone? a zone valve? does it have it's own circulator/pump?

Customer: replied 1 year ago.
it has radiant heating for the floors so has pumps for the zones
Expert:  Rick replied 1 year ago.

So you have a pump for DHW. What do you have for a relay to control the pumps?

Customer: replied 1 year ago.
I dont no!!
Expert:  Rick replied 1 year ago.

Well I suspect this may be a relay not a boiler issue. I can't help you if you can't tell me what you have for equipment. Your best bet may be to call in a pro

Customer: replied 1 year ago.
I dont think you have work on this type of system!!! Sorry
Expert:  Rick replied 1 year ago.

I've worked on more of these systems than I can count. I'm completely blind here and if you can't provide the info I need I can't help you. With no errors showing your problem is probably not boiler related.
